Patent GB-791410-A (GB)
Title: Separation of potassium and sodium ions from a mixture of sodium and potassium chlorides
IPC: C01D7/16
Filed: 1955-12-14
Abstract: Sodium is recovered in the form of its bicarbonate, from an aqueous solution containing sodium and potassium chloride by the addition of solid isopropylamine bicarbonate in an amount substantially stoichiometrically equivalent to the sodium chloride present in solution thereby precipitating substantially only sodium bicarbonate. The solution is preferably saturated at 20 degrees with respect to the chloride ions.  After addition of the isopropylamine bicarbonate the solution may be stirred at room temperature for about 15 mins. The mother liquor may be treated for the recovery of the potassium either as chloride or as bicarbonate.  For example potassium bicarbonate may be precipitated by the addition of further potassium chloride in an amount at least equal to that already present in solution and isopropylamine bicarbonate, or isopropylamine and carbon dioxide. Alternatively, further isopropylamine bicarbonate alone may be used.  In a modification the sodium and all or a portion of the potassium is precipitated as a mixture of sodium and potassium bicarbonate by the addition of an appropriate amount of isopropylamine bicarbonate.  Residual isopropylamine bicarbonate in solution may be reacted with further sodium chloride.  Residual isopropylamine hydrochloride may be treated in known manner for the recovery of isopropylamine which may be recycled to the process.  The solution containing sodium and potassium chloride may be prepared from sylvinite by dissolution of the mined ore or by direct dissolution of the unmined ore at ordinary temperature.  The ore may be treated with hot water or brine preferably at 100 DEG  C. so as to incompletely dissolve the sodium chloride content of the ore and the resulting solution cooled to selectively crystallize potassium chloride, the mother liquor being treated for the recovery of sodium bicarbonate and the crystallized potassium chloride then being returned to the solution for the recovery of potassium bicarbonate. Specification 703,526 is referred to.

Title: Improvements in or relating to automatic pressure fluid distributors for vehicle suspensions
IPC: F15B13/04
Filed: 1959-10-30
Abstract: 936,001. Equalising load on wheels. FABBRICA ITALIANA MAGNETI MARELLI S.p.A. Oct. 30, 1959 [Nov. 24, 1958], No. 36899/59. Class 108(2). In vehicles having pneumatic suspensions and an auxiliary axle, a valve controls the pressure in the auxiliary axle pneumatic suspensions in accordance with the pressure in the rear axle suspensions. Pipe connections A and B from the rear axle suspensions and the auxiliary axle suspensions respectively are in communication via a valve 2 controlled by a hollow push rod 4 fixed to a central plunger 1. The push rod can slide through a fluid-tight gland 5, in a wall E which separates a cylinder chamber F from a chamber G. A compression spring 6 is interposed between the inside surface of the plunger 1 and the wall E. The cylinder 3 has abutments 7, 8 to limit the movement of the plunger 1. When the vehicle is carrying the load at which it is desired to put the auxiliary axle under load, the pressure in the pipe A (and also therefore in the chamber C) is great enough to force the plunger 1 back against the action of the spring 6, and the push rod 4 opens the valve 2. When the valve 2 is open the third axle suspensions are under pressure and can carry load. As load on the vehicle increases, the pressure increases in the front and rear axle suspensions and therefore also in the auxiliary axle suspensions. When the vehicle load returns to a value lower than that which brought the auxiliary axle into operation, the spring 6 forces back the plunger 1, and the valve 2 closes. The fluid from the auxiliary axle suspensions escapes into the atmosphere through the bore S and the wheels of the auxiliary axle return to their rest position.
